same in turn heating any vapor intlie carbureter and generating therefrom a hot gas which moves up the intake manifold and also into the storage receptacle 25. However, while the throttle 23 is closed such gas goes to the receptacle. throttle is opened a supply of hot gas is ready for admission to the cylinders, said gas flooding the combustion chambers and readily igniting to cause easy starting. Thus, controlled by the engine demand, after starting, and whenever the throttle is opened, hot gas is always supplied to the engine, along with a supply of preheated fresh air through the pipe 28 and universally mounted horn 29. If the throttle is momentarily closed the supply of hot gas generated by the heater is stored in the hot receptacle 25 where the exhaust manifold functions to keep the receptacle heated.

From this disclosure it will now be seen that structure has been provided which achieves all of the desirable objects of the invention heretofore recited.

It is the intention to' cover all such changes and modifications of the illustrated form of the invention as do not materially depart therefrom as isindicated in the appended claims.

What I claim is: l. The'combination with'an internal combustionengine having a carbureter andintake manifold, :of a heater for generating the carbureter mixture into a hot gas, a hot storage receptacle, means for-passing said hot gas to, the intake manifold, a -pipe The moment the intake manifold, a conduit directly connectmg the carbureter and manifold, of a heater disposed in said conduit for generating a hot gas from the carburetermixture as it communicating with the atmosphere and-extending into the hot receptacle, and a horn for directing air currents to the pipe.

2. The combination with an internal combustion engine havinga" carburetor, intake manifold and" a conduit between the two, of a heater located in the conduit between the carbureter and manifold, a valvein the conduit between the heater and the intake manifold, an exhaust manifold, a pipeleadmg. from the condult, an enlarged storage receptacle connected to said pipe and car-:
